The ALP says the move will strip organisations like the North Australian Aboriginal Justice Agency (NAAJA) and the Central Australian Aboriginal Legal Aid Service to the bone.

NAAJA chief executive Priscilla Collins said the cuts would take the service back to 2008 funding levels.

"People are not going to have access to justice, which means people are going to be going to court unrepresented," she said.

"It is going to increase the incarceration rate and then it is going to clog up the justice system."

Opposition Leader Tony Abbott weighed in to the argument later in the day and said the funding cuts to Indigenous legal services would affect bureaucrats and not front-line services.

"What we are going to do is take a modest saving from Indigenous bureaucracy," he said.

"I'm perfectly happy to defend that because we don't want more bureaucrats roaming around; we want more people actually delivering services and we want to be funding a better life for Aboriginal people."

Labor's federal candidate for the seat of Solomon accused the Coalition of playing a cruel hoax on voters in Darwin and Palmerston.

Luke Gosling says the figures are missing key projects for the Top End, including funding for the proposed Palmerston hospital.

"It is unbelievable," he said.

"They have been playing catch-up on the Palmerston hospital but now it seems that there is no funding committed by the Coalition for the hospital."

Both Labor and the Coalition have pledged $110 million to build the proposed hospital.

Shadow Health Minister Peter Dutton denied Mr Gosling's claim.

He said money for the hospital had already been set aside.

Health Minister Tanya Plibersek said the Coalition has only $70 million costed for the project because it was using Government figures from before additional funding commitments were made.

But Mr Dutton told ABC Local Radio the full $110 million would be delivered.

"We committed that money, we will stand by that money," he said.

"I promise you that if Tony Abbott and Natasha Griggs are elected on Saturday, we will deliver that $110 million."
